Know Your 400G Transceiver | Juniper Networks
Fiber type and reach—The fiber type specifies the type of optical fiber (single-mode or multimode) compatible with 400G transceivers. The reach provides the maximum supported distance or range
Which type of optical fiber is used in the optical module
Optical modules typically use either single-mode or multimode optical fibers, depending on the transmission distance and data rate requirements.Single-Mode Fiber (SMF)Single-mode fibers have a small core diameter, usually around 8–10 µm, allowing only one propagation mode of light. This minimizes modal dispersion, making SMF ideal for long-distance and high-speed transmissions, such as in data centers, metro networks, and telecom backbones. Optical modules designed for single-mode fiber often operate at wavelengths of 1310 nm or 1550 nm and can support distances from several kilometers up to tens of kilometers, depending on the module type and power output .Multimode Fiber (MMF)Multimode fibers have a larger core diameter, typically 50 µm or 62.5 µm, which allows multiple light modes to propagate simultaneously. MMF is suitable for shorter distances, such as within data centers or campus networks, due to higher modal dispersion. Optical modules for multimode fiber usually operate at 850 nm or 1300 nm and support distances ranging from a few meters to a few hundred meters, depending on the fiber type and module specifications .Optical Module CompatibilityOptical modules, such as SFP, SFP+, QSFP, and XFP, are designed to interface with either single-mode or multimode fibers. The module contains a TOSA (Transmitter Optical Subassembly) and ROSA (Receiver Optical Subassembly) that convert electrical signals to optical signals and vice versa. The choice of fiber type is determined by the module's intended application, required data rate, and transmission distance .SummarySingle-mode fiber: Long-distance, high-speed, 1310/1550 nm, core ~8–10 µm.Multimode fiber: Short-distance, moderate-speed, 850/1300 nm, core 50–62.5 µm.Optical modules are designed to match the fiber type for optimal performance and minimal signal loss . Choosing the correct fiber type ensures reliable communication, efficient signal transmission, and compatibility with the optical module's specifications.

OverviewUsesHistoryPrinciple of operationMechanisms of attenuationManufacturingPractical issuesSee also
Optical fiber is used as a medium for telecommunication and computer networking because it is flexible and can be bundled as cables. It is especially advantageous for long-distance communications, because infrared light propagates through the fiber with much lower attenuation compared to electricity in electrical cables. This allows long distances to be spanned with few repeaters.
